February 9 2006 scribe-Kimberley Besyk

make a sentense with the words expression, equation, algebra, 3x+6=14 and 2x-5.
An algebraic expression like 2x-5 is a pattern. There are many answers

An algebraic expression has only ONE (1) answer.

One step problem solving

x+6=9-6
-6
x=3
3+6=9

1)isolate the variable
2)cancel out using an opposite
3)balance
4)substitute to check answer

x+8=20-8
-8x=12
12+8=20

Hint--> when canceling integers you need a result of 0.

-13+y=40+13
+13
y=53
53+13=40

This is different *13-x=12* .

The next scribe is Josh

Good job Kimberley. And to answer your question... It's the same formula to figure it out while multiplying and dividing. Just remember BEDMAS (Brackets, Exponents, Division or Multiplication, Addition or Subtraction)

that was a pretty good scribe post. however, there was just one small problem... You said that an expression had only one answer, when it is an equation that has only one answer. AN expression has an infinite nymber of answers
